A part is a database object that represents a physical component or assembly in the product structure of a manufactured product. A part is used as the container for all information that describes or defines that component (for example, CAD models, worksheets, drawings, and document images). The Mathcad object is then used to construct product structures in Windchill. Specifically, the database object type is wt.part.WTPart. For simplicity, in Windchill this is displayed to the user as Part. For the purposes of this section, the term part is used to refer to this object type.
